FILTER.

SPECIFICATION forming part of Letters Patent No. 343,519, dated June 8,1886.

Application filed June 27, 1885.

To all whom it may concern.-

Be it known that I, ALFRED J. GIBERSON, of the city of Boston, in thecounty of Suffolk and State of Massachusetts, have invented certain newand useful Improvements in Filters; and I do hereby declare that thefollowing is a full and exact description thereof, reference being hadto the accompanying drawings, forming apart of this specification, andto the letters of reference marked thereon.

My invention relates to the construction of the filter, the meansemployed to keep the filtering chamberand medium flooded, the means fordistributing theflow as it passes to the filtering medium, the relationand combination of parts, substantially as hereinafter more specificallyset forth and illustrated.

Figure 1 is a perspective view showing the distributing device attachedto the removable ring bearing the strainer. Fig. 2 is a similar view ofthe same parts in an inverted posi- Fig. 3 is a sectional view of thesame. Fig. 4 is a smaller view showing a plan of the strainer, &c. Fig.5 is a similar view of the parts inverted. Fig. 6 is a central verticalsection of the filter-case, exposing in eleva tion the parts shown inprevious figures and illustrating their position and relations. Fig. 7is a sectional elevation of the filter case or body, exposing to viewthe connection and re lations of the swivel stand-pipe or reservoiranddelivery and its arrangement. Fig. 8 is a plan of the latter device,Fig. 9 is asectional View of parts Z and 11..

Like letters refer to the same or corresponding parts in all thefigures.

Referring to the drawings, observe the filtercase has the usualscrew-socket in the ends for attachment to a faucet-nipple or othersupply. In and below this socket, at 'each end, is an other socket orrabbet fitted to receive ring a. Ring a is a support for the strainer,which is shown by cross-lines. It has provision for fastening into theabove-mentioned socket, in the pin 7? and inclined groove (1 in therespect ive parts. A notch or upright groove at the end of the inclinedgroove allows the pin to enter, and a partial rotation of one partrelatively to the other makes them fast together, and the reversemovement unfastens them. The outer end of ring a has a beveled shape,

which allows it to come in cont-act with a leather, rubber, or otherelastic cushion for the faucetbib, and avoids any danger ofobjectionable contact with the faucet-bib or other connectedsupply-pipe. To this ringais also attached or suspended a distributingplate or disk, 0, of any convenient and desirable shape. Thisdistributer c has arms or open-work rim, by which it is attached to thering a, so that whenever the ringwand strainer is removed thedistributer comes away with it, and when replaced the distributeristhereby replaced, by which means the distributor is never in the way toobstruct in the removing or replacing of the filtering medium ormaterial placed between the two strainers in the body or case of thefilter.

The connection between ring a and the distributer 0 may be made invarious ways; but I prefer at present to turn a rabbet in the end of thering, and then in a lathe, by the spinning process, after placing thedistributer in the rabbet, to turn down upon its arms, rim, or outeredge the thin rim of the ring left in making the rabbet, as see Fig. 3.The distributer being stamped out or otherwise made with separate arms,or with the outer end of the arms joined to a rim or continuous ringpartto be thus secured in the rabbet, this distributer causes the enteringflow to be distributed between the arms or parts connecting it to thering to all parts of the upper portion of the filtering material, whenceit evenly percolates through the entire body.

The filter shown is of the class adapted to be unscrewed from thesupply, reversed, and the other end screwed on, thus reversing thedirection of flow relatively to the filtering material, and thus washingout the accumulated impurities.

To prevent, during intervals of rest, the exposure of impurities in thefilter to the decomposing influences of the air, I provide for keepingthe filtering chamber and material flooded constantly. To do this, Iconstruct the filter with a lower part, Z, formed with a screw, toscrew.-into the bib-socket against a cushion, m, of leather, rubber, orother elastic material.

Into this part Z is fitted, so as to swivel or turn on a vertical axisor center, the reservoir n, the outer and upper part of which isprovided with a delivery-orifice, 0, the deliveryorifice being above theupper bound ofthe filtering material or chamber. When the filter hasbeen screwed onto the supply'nipple, the reservoir and delivery a 0 isturned orswiveled in any desired direction most convenient to receivethe outflow. NVhen the filter is unscrewed from the supply,to reverseit, the part Z is also unscrewed, and after the filter is screwed on andwashed out, part 1 is screwed in again and turned in the desireddirection. Thus two useful functions are performed, flooding the filterconstantly for one, and directing the discharge in any direction atpleasure, and I may add a third, delivering the outflow at a heightconvenient for high receivingvessels.

The filter breaks the force of highpressure supply and gives a smoothstream without spatter at a high point of delivery. The parts are madeof the usual materials.

I claim- 1. A filter made reversible by means of screw h at each end,and having the strainer and distributor attached to each other andremovable together, substantially as described.

2. The removable strainer and dislributersupporting ring, constructedwith the outer beveled edge, f, substantially as described.

3. The removable fi1ter-strainer ring a, as constructed with bevelededge f, groove d, and attached distributor a, substantially as shown.

4. The removable filter-strainer ring a, as constructed with theattached distributor c and groove (1, in combination with pin 2' and thecase g, substantially as described.

5. The removable filter,as constructed-via, with case 9, screws'h, pin1', removable ring a, having groove (1, strainer, and attacheddistributer c, substantially as described.

6. The reversible filter-ease g, in combination with the removable partZ, reservoir a, made to swivel, two strainers, and intermediatefiltering material, substantially as described.

7. A filter, as constructed, having case 9, strainers b, anddistributers 0, removable togethcr, removable part I, swivel reservoirn, and delivery 0, substantially as described.
